You can't move for coffee shops these days, trust me. They're everywhere. Coffee shops (and restaurants and charity shops) have exploded in numbers over the past 5-10 years, as the economy has shifted towards the high street being more of a leisure desitination than retail environment as more & more shopping either moves online or out-of-town.
I wouldn't have minded some coffee shops on the High back then. It's been about five years since I've been back. The sort of place where nothing changes and everything changes. Paradox intended.
